Carly Fiorina, a Republican rival of President Trump's in the 2016 presidential primaries, also suffered his insults over her personal appearance.

Carly Fiorina said on Thursday that President Donald Trump has reached “a new low” with his recent attacks on Stormy Daniels, a porn star who claims she had an affair with Trump in 2006 and has sued him for defamation.

“I think the habit of insulting one’s political enemies is unfortunately long standing in this country, and he has brought it to a new low ― a fine art,” Fiorina told CNN’s Anderson Cooper.

“There’s no question that in politics personal insults work and they rile people up,” Fiorina said, adding that she thinks the insult “diminishes” the Oval Office.

“I think it’s beneath him, and I think it diminishes all women ― but it works,” the former Republican presidential candidate said.

Trump on Tuesday called Daniels “horseface” in response to a federal judge’s decision to dismiss her defamation suit against him.

“Federal Judge throws out Stormy Danials lawsuit versus Trump. Trump is entitled to full legal fees.” @FoxNews Great, now I can go after Horseface and her 3rd rate lawyer in the Great State of Texas. She will confirm the letter she signed! She knows nothing about me, a total con!

“Look at that face,” Trump told the magazine. “Would anyone vote for that? Can you imagine that, the face of our next president?! … I mean, she’s a woman, and I’m not [supposed to] say bad things, but really, folks, come on.”

When Cooper asked what she thought of Trump’s “horseface” remark, Fiorina replied, “Here he goes again.”

“When people were shocked at Donald Trump’s comments about my appearance, I wasn’t,” she told Cooper. “He wasn’t the first man to make comments about my appearance, positive or negative, and he won’t be the last man to do so.”

“There’s no doubt that the office of the presidency is diminished when the occupant engages in this kind of insult over Twitter,” she told Cooper.

“On the other hand, when I think about the people involved here ― Stormy Daniels, her lawyer, Donald Trump ― I honestly think they’re all birds of a feather,” Fiorina said. “They’re all in show business. While she’s talking about his private parts, he’s talking about her face and they’re all getting a lot of publicity.”
